A free, simple and Open Source daemon designed to save GNOME's session settings.
GNOME Settings Daemon (gnome-settings-daemon) is an open source and simple daemon designed to handle the session settings of the GNOME desktop environment.
The GNOME Settings Daemon package is required by many important GNOME applications, such as GNOME Shell, GNOME Control Center, GNOME Tweak Tool, and GNOME Disk Utility. Also, third-party applications, such as the Ubuntu One GNOME client, use the GNOME Settings Daemon program to save settings.
GNOME Settings Daemon is distributed as a core part of the GNOME desktop environment, and it can not be used for any other desktop environment. It is also used by the Ubuntu Linux operating system to save its session settings.
